Sound is a form of energy. And phones use cell/battery to run. They store electrical energy. While we talk over the phone we give out sound energy. We can have a small device which converts sound energy to electrical energy and charges the cellphone batteries while we speak. It can even be charged in a theatre, pub, discos, traffic signals basically anywhere with a decibel level.

Would it be nice to just look at your watch whenever your cellphone rings. The watch will have bluetooth capability that talks with the phone and displays the CALLER or the MESSAGE sender (better yet with the message) before I even take my phone out from my bag or pocket.

When you put a call thru to someone whose line is busy or they have call waiting but choose not to answer your call why not have some device to automatically connect you to their answering machine, or maybe this is already available.

Looking to create a secure environment in nursing home rooms for telephone fraud prevention without the necessity for remembering lengthy passwords or using calling cards with long numbers to dial. Perhaps a telephone that records the authenticated voice and stores in the unit. Then, no dial tone is given until the voice verification process authenticates the speaker using the telephone.

A pay per use, water proof, bullet proof, hurricane, flood, plague of locusts proof, emergency phone. A life or death survival phone that will make your S.O.S be heard no matter where, no matter what. Free or cheap to have, but you pay out the wazzoo if you use it.

How about a two sided TV screen, shaped like a letter V? It would be two TV's joined to move into separate directions. It would allow two people in same room to watch different TV programs. There would be separate remotes and possibly speakers inside remote like in hospitals ... or even simple headphone speakers. Couples would not have to have TV's in separate rooms any more.

A system that allows you to phone home to your video recorder to tape television programs you may have forgotten to time or program in. Phone menu allows you to pick what channel you want and start recording... that is how simple it needs to be... anymore complicated than that and you lose most of the public who cannot even program their videos in the first place. Especially a good idea for new generation dvd recorders.

Have you ever watched a politician or other public figure on tv, and wonder how that person looks to people in other countries? Does that cool football coach look silly to people in other cultures? Likeable? Grouchy? Right now, there's no way to tell. But if people watching in other countries could submit feedback online, we could tell what they're thinking. It would be fun, and might even avert a few international misunderstandings.

I was thinking you could have something that charges your phone/ipod while you walk. Build a device that you could put in your shoe, or in your purse, or somewhere on you, that could use kinetic energy to charge your stuff.
